shoebur if a Destroyer unit, costs 1,000,000,000,000,000 Attack: 1,000,000,000 Hp: 10,000,000,000,000,000 and attack rate is 10.00 there will be no challenge for destroying star bases
there must be events in grouping the star base eg. in lv5 star base xyz is first in lv3 star base xyz is first because when any event was there all the rewards are taken by very high level star base.
